Optical Speed Measuring System - HBM T10FS Operating Manual

T10FS
The output pulse count is calculated according to the following formula:
output pulse count +
NOTE
Please make sure that when you change the pulse count, you also
change the pulse duration!
We recommend giving preference to the output pulse counts selected by
switches F1...F3. By using pulse division (switches S1...S4), it is
possible to increase the pulse tolerance stated in the specifications.
Other quantities, such as the eccentricity and the relative movement
between the rotor and the stator can affect the pulse tolerance.

7.5.2 Optical speed measuring system

NOTE
The factory setting is 360 pulses/revolution. Please make sure that when
you change the pulse count, you also change the pulse duration!
pulse duration +
The number of pulses per rotor revolution can be adjusted by means of DIP
switches S1 ... S4.
